Not the easiest razor to maneuver, and the blades they sell aren't so sharp, so it often glides over and pushes down hairs instead of cutting the hair, making you want to press down on the razor but then you cut yourself. Better safety razors out there.

Absolutely the worst razor I've ever used, the razor adjustable part, is almost impossible to use!! I wouldn't take another one if it were FREE!!!

Beware. This Supply razor is hot garbage. Got it for Christmas and my bathroom looked like a murder scene. Researched and tried to understand how to use it, which I find odd that you have to learn how to use shave equipment so it doesn't hurt you. I tried it again with a modified technique and I didn't murder my neck, I only lost like a pint of blood this time. Returning it for sure.

I have used a DE safety razor for over 30 years, specifically a Merkur 34C and for the last 7-8 years a Feather blade. The Supply Pro does not give me a quality shave. I have to do a double pass with the Pro to achieve the same closeness as my Merkur. Additionally, I find the Pro handle very clumsy and indeed requires the sleeve that must be bought separately. Unfortunately, the sleeve does not significantly improve the razor maneuverability. Lastly previous reviews noted they get 7 - 10 shaves per blade. I did not attain that performance and could feel the blade tugging after 5 shaves. I am now stuck with a 90$ razor that will just sit in the drawer.
